Kingston,Mi | Trent has the key to any successful construction, adequate preparation of the subgrade and adequate bearing strength of the soil. Http://www.concretenetwork.com/concrete/footing-fundementals/why_so... has presumed bearing strengths used in building codes.
I have several sites with 36,000 gallon tanks sitting on 60 mil hdpe over prepared soil subgrades with no concrete at all. Many posts on this forum have insinuated that NRCS and other government agencies (and private engineering firms) of over designing every practice ever requested and when the design agency says that the engineering has proven that "x" is adequate, many "experts" want it doubled or tripled. | |
